Return-to-Home (RTH)
Return-to-Home (RTH) function brings the aircraft back to the last recorded Home Point. There are
three types of RTH: Smart RTH, Low Battery RTH, and Failsafe RTH. This section describes these
three scenarios in detail.
GPS
Description
Home Point
If a strong GPS signal was acquired before takeoff, the Home Point is
the location from which the aircraft launched. The GPS signal strength is
indicated by the GPS icon (
Less than 4 bars is considered a weak
GPS signal.). The aircraft status indicator will blink rapidly when the home
point is recorded.
The aircraft can sense and avoid obstacles when the Forward Vision System is enabled and

The Return-to-Home process may be interrupted and the pilot given control of the aircraft if the
remote controller signal connection is re-established.

Aircraft cannot return to the Home Point when GPS signal is weak ( [ ] Less than 4
bars is considered a weak GPS signal.) or unavailable.

65 feet (20 meters) radius of the Home Point. Aircraft will stop ascending and immediately
return to the Home Point if you move the left stick if the aircraft reaches 65 feet (20 meters)
altitudes or beyond during Failsafe.

to set the Failsafe Altitude.
User cannot control the aircraft while the aircraft is ascending to 65 feet (20 meters) from the
current altitude. However, user can press RTH button once to exit ascending and regain control.
